Secret Netflix "trick" hack finally takes the stress out of choosing what to watch

A Windows 10 update is causing pain and anguish around the world

You might think that progress is a universal and unquestionable good. But perhaps you haven’t ever tried to install the latest version of Windows 10 and then watched disconsolately as your computer slowed to a miserable crawl.

Calciumhas potential in a number of areas, but struggles in finding a way to move electricity through an electrolyte.

It's not perfect yet, but scientists have created the best electrolyte to date.

Arecently synthesized chemicaloffers the promise of an entirely new type of battery: calcium-based, as opposed to the modern batteries that rely on lithium.

Across the globe, scientists are interested in what's coming after lithium batteries. The rechargeable batteries have become the dominant power source in any number of consumer electronics, from phones to cars. Researchpredictsthat the global lithium ion battery market will be worth $ 81.65 billion by 2021.

But with that growth comes a suite of challenges. There's thelimited physical natureof lithium's output (primarily in Latin America and China), but also from theenvironmental havocits extraction, which often requires heavy water consumption, leaves on the surrounding areas.

Calcium has the potential to act as a replacement. It's already used inlead acid batteries, which are often seen in automotive starter motors. It's the fifth most abundant element in Earth's crust and the third most abundant metal, with equal geographical resource distribution around the globe. Calcium also lacks lithium's troublesome trait of catching fire.

The challenge for researchers has been finding a workable electrolyte. Within batteries, an electrolyte is a catalyst that allows the battery to move ions from one place to another. For a battery to work, it needs to transfer ions from its cathode to its anode. Electrolytes come inmany varieties, including soluble salts, acids, or other bases in liquid, gelled, and dry formats.

Researchers at Helmholtz Institute Ulm in Germany used a salt here. More specifically, they "reacted a calcium compound with a fluorine-containing compound to create a new type of calcium salt," according to adescription inNature, which distributes theEnergy & Environmentaljournal in which the research was first published.

According to the team's paper, the new electrolyte has "wide electrochemical window and good chemical stability, which may pave the way for high-energy Ca batteries."

There's still a way to go in the research progress, with the team saying that "further improvement will be carried out by modifying the electrolyte compositione.g.solvent, concentration and additive." Now that an electrolyte has been discovered, in other words, it can be improved.

Scrolling through Netflix can often feel like a chore, especially when you kind of know what you are in the mood for but don’t know how to search for that. Well, stress no more, because this genius Netflix hack is a genuine gamechanger that will stop you wasting those precious minutes finding what you fancy.

Yep, if it’s a Tuesday evening and you fancy an understated drama from the 1950s or a mad scientist comedy or even a steamy horror film, all you need to do is type in a very specific code, and Netflix will present all the possible options. Once you’ve discovered your code – and there are over 27,002 available here– you just need to log in and then type in http://www.netflix.com/browse/genre/XXXX to the web address.

But instead of XXXX you include the five-digit code. So next time you’re in the mood for a girl power science fiction flick (Alien) or a visually striking romance (Amelie) just remember that it’s much easier with this hack.

But perhaps you haven’t ever tried to install the latest version of Windows 10 and then watched disconsolately as your computer slowed to a miserable crawl.

Windows users have claimed that the latest software update has caused major problems with their system.

The update is called Windows 10 KB4512941 and is alleged to make the CPU of victims’ computers run wild, meaning the whole system slows down, and stop them from using the Windows Search option near the start menu. It appears the problem lies with Cortana – Microsoft’s voice assistant. ‘I just installed KB4512941 and now Windows Search is broke and Cortana process in taskmanager takes 90% CPU,’ a Windows user wrote on Reddit.

Microsoft CEO Satya Nadella (Photo: AP) On Twitter, one gamer shared his pain after the update stopped his favourite game from working properly. ‘Very cool that Skyrim is broken,’ he wrote. ‘Yet another thing Windows updates has ruined for me. They’ve taken everything from me.’ Luckily, Microsoft has now turned out automatic updates meaning the software won’t be rammed onto your computer without express permission.

On Reddit, a user offered the following advice on how to deal with the problem: ‘Supposedly if you disable Cortana via registry or group policy this will happen. I wanted to leave Cortana disabled so I just renamed the Cortana folder. ‘In Task Manager, right-click the task and select open file location, rename the Cortana folder and press enter. You will get an error because Cortana is still running, you need to end the task and then quickly press the Try again button for the rename before the task restarts. ‘Note that this doesn’t fix search, it just stops the high CPU load.’

Google has issued an urgent update to plug a dangerous hole in its Chrome browser. .

The flaw lets hackers ‘execute arbitrary code in the context of the browser’.

This means attackers could view your secret data or even edit and delete it.

Hackers are always looking to access sensitive information like bank details or some naughty nugget which allows them to blackmail people.

The alleged bug was discovered by the Centre for Internet Security, which wrote: ‘A vulnerability has been discovered in Google Chrome, which could allow for arbitrary code execution. Google Chrome is a web browser used to access the Internet. ‘Successful exploitation of this vulnerability could allow an attacker to execute arbitrary code in the context of the browser.
